Log3x + log3(x2 + 2) = 1 + 2log3x

x = 1 , 2.

Step-by-step explanation:

I am assuming these are logs to the base 3.

log3 x + log3 (x^2 + 2) = 1 + 2log3x

-log3 x + log3 (x^2 + 2) = 1

log3 [ (x^2 + 2) / x] = 1            NOTE: 1 = log3 3, so:

log3 [(x^2 + 2) / x] = log3 3

(x^2 + 2) / x = 3

x^2 - 3x + 2 = 0

(x - 1)(x - 2) = 0

x = 1 , 2.

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
